Besides Zelda/BOTW, which Nintendo series had the best transition to HD?

Man, that poll is stacked with all-time great games :)

Is this about the greatest technological leap or simply the best game that happens to be HD? If it's the former, I will echo others and say Xenoblade Chronicles X. It remains a very impressive feat of design and engineering, considering the limitations of WiiU.

If it's the latter, I will go with Mario Kart 8, which in 2014 was the best Mario Kart game by a significant margin, despite the anemic battle mode. And that margin has only gotten more massive thanks to Mario Kart 8 Deluxe + the Booster Course Pass.

I meant it as which is the best game, but it being an impressive leap can be a part of that; with say Xenoblade for instance a bit part of its appeal for me was the technological evolution over what was possible in the first game in terms of world design.
